Abstract: PURPOSE:To reduce the memory capacity to be used for data correction and use a memory which gains a margin for another purpose, and to improve the total throughput of a device by sending held correction data from a holding means to the host side and performing a data correcting processing on the host side. CONSTITUTION:Once a print request is received from the host 110, whether or not the host side 110 has a data correcting function, is inquired through a host i/f 104. Then, an answer is received from the host side to judge whether or not the host side has the data correcting function. When the host side has the data correcting function, CMY correction data stored in a ROM 2 are sent to the host side so that the data are processed on the host side. When the host side does not have the data correcting mechanism, on the other hand, the CMYK data are corrected. The corrected data are sent to an engine 108 through i/f 106 and printed. Consequently, when the host side has the data correcting mechanism, the capacity of the buffer memory 107 used for the data correction is made reducible.
